Looking to fit a new seatpost to my bike

Frames is Reynolds 531 which uses a traditional bolt through the frame (opposed to a clamp) to secure the post

Question is can a carbon post be used on the is type of frame ? is it likely to be crushed as it is tightened,

the post I’m looking at is full carbon and not a wrapped alloy one

Why do it? It's like putting 3 spoke alloys on an E-Type... :shock:

Hi Hamster

The bike is pretty much all black (with a few polished bits here and there) and I am looking for a gloss black seatpost with polished clamp and no logos, I couldn’t find anything in metal which ticked all the boxes but the more i think about carbon post on this particular bike the more I like it :D plus the carbon weave is pretty subtle and looks black from a distance

I take your point about modern wheels on an old car however it doesn’t always look bad :wink:

But that's some kind of re-issue P1800 concept, not the original, surely?
The flush glass roof and tail detail looks all wrong :?

The only post I can think of is a USE, maybe also some of the wet look black Ritchey stuff

Thanks for the info i'll do a search for the USE post :D

regarding the car yes it is a render but the car will be built round a P1800 you can read the full article here

I think it looks great on the BBS LM wheels :)

Back on topic, does anyone think I will have issues with this post / frame combo?

You could do it if you REALLY had to, assuming the post is the correct size of course.
The post will fail before the frame, which is good.

I took my post out of my other bike (27.2) and i couldnt get it in, saying that the original one seemed almost as hard (didnt want to force it as it my be coming back out later in the week)
